DOOR OPERATING AND LOCKING DEVICE.

Specification of Letters Patent.

Patented Apr. 15, 1919.

Application filedMay 11. 1915. Serial $10,2 7,437.

To all whom it may concern:

Be it known that I, WALTER S. RYAN, a citizen of the United States ofAmerica, and a resident of the borough of Manhattan, city, county, andState of New York, have invented certain new and useful Improvements inDoor Operating and Looking Devices, of which the followingis aspecificaating mechanism whereby a plurality of doors may be selectivelyoperated by power transmitted from a common source.

Another object is to provide mechanism, having a controlling means, formoving a door in two directions, which mechanism, when it has moved thedoor to its limiting position in one direction under one adjustment ofsaid controlling means, is automatically set to move the door in theopposite direction upon a change of adjustment of said controllingmeans, and, further, to provide additional means for setting saidmechanism to move the door in the opposite direction, said last-namedmeans being operable at will and preferably being rendered inoperativewhen the door reaches a limiting position and rendered operative whenthe door moves therefrom.

Other and further objects and advantages will appear from the'followingdescription, taken in connection with the accompanying drawings formingpart of this specification and be pointed out in the hereunto-appendedclaims.- j

I have shown and described a construction of a character similar to thatshown and described herein in m'ycopending application, Serial Number27,436, filed May 11, 1915, for door operating andlocking devices.

Referring to the drawings accompanying the description of thisinvention, in" which like reference characters indicate similar P 2Figure 1 is adiagrammatic' view of a preferred form of a door-operatingand locking mechanism embodying my inventionj Fig. 2 is a cross-sectionon the line 2- 2 of Fig. 1;

Fig. 3 is a diagram of the Wiring of the electrical mechanism of Fig. 1;and Fig. 4 isa partial cross-section on the line 44 of Fig. 1.

In the embodiment of my invention herein disclosed, a main power source,comprising a rotating shaft, is provided. The doorznoving mechanismcomprises a shaft and means for; rotating said shaft in either directionfrom the main power shaft. The shaft included in the door-movingmechanism carries a worm which cooperates with a nut. The nutis attachedto the door in a way which will permit movement of the nut relatively tothe door after the door reaches its limiting position. A locking meansis provided for the door which is operated by the movement of the nutafter the door reaches its limiting position. The mechanism whichtransmits rotation to the door moving shaft from the main driving shaftis con trolled by electrical mechanism. Theelectrical mechanism iscontrolled by circuits which include an automatically operated preparingswitch which is operated by movement of the nut after the door reachesits limiting position, and the circuits are also controlled by amanually operated switch One of the circuits includes a switch operatedby the door to render that circuit operable after the door leaves one ofits limiting positions. The same circuit includes an electromagnet foroperating the preparing switch. The manually operated controlling switchis also included in this circuit, and the circuit is so arranged thatafter the door leaves one of its limiting positions the preparing switchmay be operated at will without waiting for the door to reach itslimiting position.

In the embodiment of my invention herein disclosed, a main power shaft1, which preferably comprises a number of sections connected byuniversal joints 2, is mounted for rotation in pedestals 3 and 4 andcarries a driving pinion 5. Mounted in the same pedestals for rotationand for limited axial movement is the door-moving worm shaft 6. Near theends of this shaft, which are mounted in the pedestals 3 and 4, arefixed collars 7 and 8, respectively, and springs 9 and 10 are placedaround the shaft and positioned axial movement. Coiiperating with theworm 6 is a nut 11, on which is mounted an extension in the form of aneye 12'. The door 13 is provided with hang'ers14', on which are rollers15, which ride on a track 16. Between the hangers 14 extends a bar 17,which fits loosely within the eye 12. Springs 18 and 18 fit around thebar 17 and are positioned upon opposite sides of the eye and between theeye and adjacent hangers 14.

It'will be seen that the rotation of the shaft 6 will cause a backwardor forward motion of the door, and that the shaft may continue to rotateand move the nut against the pressure of the springs 18 and 18 after thedoor reaches a limiting position.

In order to rotate the shaft 6, a controlling mechanism is providedwhich includes mechanism for transmitting rotation of the main shaft tothe door-moving shaft and means for controlling the transmittingmechanism; A yoke 19 is journaled on the shaft 6. On the shaft 6 thereis keyed a pinion 20, and pivoted on the yoke and meshing with thepinion 20 are the pinions 21 and 22. The pinion 21 is of such a sizethat when the yoke is rocked about shaft 6 from its vertical positionthe pinion 21 will mesh with the pinion 5 keyed to the shaft 1 to impartrotation in one direction to the shaft 6; Pivoted to. the yoke 19 andmeshing with the pinion 22 is a pinion 23, which is so positionedthatwhen the yoke is rocked about the shaft 6 in the opposite side ofits normal vertical position the pinion 23 will mesh with the pinion 5on the shaft- 1 and, through the pinions 22 and 20, impart rotation tothe shaft 6 in the opposite direction. A lever arm 24 forms the upwardextension of the yoke 19, and springs 25, attached to opposite sides ofthe arm 24, hold the yoke in normal vertical position, so that neitherpinion 21 nor 23 meshes with pinion. 5.

In order to rock the yoke about the shaft 6, an electromagnet 26isplaced on one side of the arm 24, and an electromagnet 27 is placed onthe other side of the arm 24-, so that, when theelectromagnet 26 isenergized, power will be transmitted from the shaft 1 to the shaft 6through the pinions 5, 21 and 20, and, when the electromagnet 27 isenergized, power will be transmitted from' the shaft 1 to the shaft 6through the pinions 5,

22 and 20.

In order tocontrol the energizat'ion of the magnets 26 and 27, thefollowing circuits and switches are provided. The current is led fromthe source by the wire 28 to the cut out switch 29, which willhereinafter be described, and by the wire'29. to the switch arm 30' ofthe preparing switch, generallyindicated by 31. From onecontact 32'ofthe preparlng switch current is led to the electromagnet 27 bythe wire32, andfrom the electromagnet 27 the wire 33 leads to one point 34 ofthe three-point operating switch or controller 35. From the center point36 of the switch 3'5'the wire 37 leads back to the source Fromthecontact 38 of the preparing switch 31 the wire 39 leads to the magnet'26 and the wire 40 leads from that magnet to the third point 41 of thecontroller A small: lamp 42 is connected across the points 36 and 41,and a small lamp 43 is connected across the points 34 and 36 of thecontroller 35. r y 7 If the'preparing switch 31 is'in the position shownin the drawings, and the arm 44 of the controller 35 is swung overaboutthe point 36 to contact with the point 34, the

the collar 46 loosely mounted onthe rod 47 which slides in pedestals 4and 51 and compresses the spring 48, which is mounted on the rod 47 andkept from sliding thereon by the collar 49adjustably held on the'shaftby the screw 49. After the spring 48'is sufficiently compressed, thespring 50, mounted on the top of the pedestal 51- and having an offset52, is bent up so that the offset 52 slips out of the notch'53 in theblock 54 mounted on the rod 47, by the action of the sloping sides ofthe notch 53 against the offset 52."

The rod 47 moves tothe rightas the spring 48 is compressed and theoffset 52 drops into the notch 55 in the-block 54. As the rod 47' movesto the right, it carries with it the link 56 attached to it, and thelink 56 being attached to the arm 30, the arm30 is swung over so that itcofiperates with the contact 38 of the preparing switch 31.Thisestablishes a circuit from the supply wire 37 through the lamp 42,wire 40, magnet 26 wire 39, contact 38, arm 30, wire 29 and wire 28,back to the source. The lamp is a high resistance lamp, and too littlecurrent flows to energize the magnet26 enough to swing the arm 24, butthe lamp 42 is illuminated and indicates that the doorhas reached itsclosed position. 7

then the arm 44-is swung over on to the point 41, lamp 42 isshort-circuitedand goes.

out, but the magnet 26 is energized, and power is transmitted from theshaft 1.. to shaft 6 through the pinions5, 21 and 20, and the shaft 6 isrotated to open the doorgand, when the door reaches its limiting openposition, the actuating member 45 strikes against the collar 57,slidable on rod 47, and conn presses the spring 58 which surrounds therod 47 and is kept from sliding thereon by the collar 59 held inposition on the shaft'47 by the screw 60. After the spring 58 is sufii-5 ciently compressed, the offset 52 of the spring 50 is forced out ofthe notch 55 in the block 54, and the rod 47 moves to the left, and thepreparing switch 31 is moved to its initial position, and the circuit isestablished through the lamp 43, showing that the door has reached itsopen position.

It will be seen in each case that the switch 31 is automatically movedbythe door and prepares a circuit for energizing one of the magnets 26 or27 by closing the circuits of those magnets at one point, while the controller or operating switch 35 closes the circuits of the magnets 26 and27 at another point to energize them. i Pivoted on the pedestal 51 at 61is a lockoperating bar 62, which has an oifset end part, the parts beingjoined by the oblique portion 64. Pivoted to the end of the bar 62 at 63is a lock-operating rod 65, which carries a lock 66, which dropsdowninto the opening 67 formed in the door 13. Fixed in the operatingmember '45, with their centers on a line perpendicular to the obliqueportion 64 are pins 68, cooperating with the top and with the bottom,respectively, of the lock-operatingbar 62. As the actuating member movesalong until the oblique portion 64 rests between these pins 68, thelockoperating rod is allowed to drop to lockthe door" The upper end ofone ofthe door hangers 14 is formed into a cam 69, which cooperateswith. a roller 70 on the lock-operating rod 62 to prevent theloclco-perating rod from dropping before it is positioned within theopening 67 in the door. Mounted on the actuating member 45 are rollers71, which cooperate with the rod 47. The u-pper: one of these rollersmoves underneath a block 72 attached to the'frame of. the door, so thata force applied to the lock-operating rod 66 and tending to lift itcannot possibly raise the lock-operating bar 62.

. If the movement of the door is obstructed, the shaft 6 will continueto rotate until an unusual axial thrust is imposed upon it and one ofthe springs 9 or 10, which are designed to resistthe normal axialthrust, is compressed and the shaft 6 moves axially. Collars 73 arefixed on the shaft 6 and accommodate between them one end of the lever74, which is pivoted at 75. The other end of the lever has attached toit the link 76, which is attached to and oscillates the cut-out switch29 about the point 78 at which 6.0 it is pivoted. The cut-out switch 29comprises an inverted U-shaped sealed glass tube, which contains enoughmercury to fill thelegs of the tube and provide a contact between them.when the tube forming the ca bottom. of the Ultis horizontal. When theswitch 29 is oscillated about the pivot 7 8, the contact is broken, andthe current passing into the bottom of one leg by the wire 28 and out ofthe bottom of the other leg by the wire 29 ceases to flow. Across theterminals of the switch 29 there is connected an alarm bell 77, so that,when the motion of the door is arrested, the current is diverted throughthe alarm bell 77, and notice is given that the door is not moving.

In order that the door may be opened after it has been part way closedwithout moving the door to its completely closed position in order tooperate the preparing switch 31, a separate means is provided foroperating that switch at will after the'door has left its limitingposition. It will be seen that when the door is open and the switch 31is in the position shown in Fig. 3, the magnet 26 cannot be energizeduntil the door is entirely closed and the arm 30 of the switch 31shifted over to the contact 38. In order to shift this arm 30 withoutentirely closing the door, an electromagnet 79 is provided to move therod 47 just as the actuating member 45 would move it if the contactmember were pushed up against the collar 46. The circuit of this magnet79 comprises the wires 80 and 81 and closes the gap between the arm 30and the contact 38 when the arm 30 is in a position to operate mechanismto close the door. The wire 81 includes a spring-closed switch 82, whichis held open by the contact of the hanger 14 of the door with the rod 83attached to the contact piece 84 of the switch, which contact piece isnormally held against the terminals 85 of the wire 81 by the spring 86.

' It will be seen that, if the arm 44 is swung over on to the contact34, the magnet 27 will be energized and the door will start to close.If, however, it is desired to open the door again, the arm 44 may beswung over on to the contact 41 and the magnet 79 is energized, whichcauses a shifting of the rod 47 and the preparing switch arm 30, and thecircuit of the magnet 26 is completed and the door will be opened.

In order that the rod 47 will not be shifted tothe right by the magnet79 immediately after the actuating member 45 has caused a shifting ofthe rod 47 to the left when the arm 44 has been swung to the contact 41to open the door, the circuit of the magnet 79 is caused to break, asabove described, by the switch 82, which is operated by the door when itreaches open position.

The wire 80, which leads to the magnet 79, is connected to the wire 28,and the wire 81, which leads from the magnet 79, is connected to thewire 39. It will be seen, therefore, that, if the movement of the dooris obstructed and the cut-out switch 29 is rotated, so that the circuitthrough the mercury in the cutout switch is broken, the circuit of themagnet 79 will not be broken, but will be energized as soon as the arm44 is swung over on to the point 41, if the door is actually in transitand switch 82 is closed.

Although one magnet 79 and its controlling circuit has been illustratedand described, it will be apparent to those skilled in the art that asimilar magnet might be applied to the opposite end of the rod 47 fromthat at which magnet 79 is applied and be connected from the wire 28tothe wire 32. With such a magnet, the operating mechanism could bereversed if the opening movement of the door was obstructed.

It will also appear to those skilled in the art that the magnet 7 9might be dispensed with entirely, for the circuit formed by the wires 80and 81, which circuit is closed by the switch 82, could be depended uponto energize the magnet 26 to cause a reversal of the movement of thedoor, if it had low enough resistance.

While a positive locking member has been illustrated and described, sucha locking means is not absolutely necessary, because the door is drivenby a worm-and-nutgearing and the door could not be moved unless theshaft were rotated by some outside force, so that the driving mechanismis itself a locking mechanism.

It will be seen that means for operating the preparing switch has beenprovided which is dependent upon the position of the door, for thismeans is not operative when the door is at its limiting open position,and it is only operative when the door has moved from its limitingposition.
